| 3 | 29 | Maximilian Seesslen | Device that records data from sensors that are connected via CAN directly via I2C. |
| 4 | Results can be read via USB or retransmission can be triggered via CAN. Measured data have correct timestamps. |
||
| 5 | |||
| 6 | 35 | Maximilian Seesslen | generic CAN-controller: Plant-lamps, light-alarm-clock, auto-off of Mainswitch, controll pumps |
| 7 | 34 | Maximilian Seesslen | |
| 8 | 35 | Maximilian Seesslen | (Also want to test memory mapped QSPI-flash.) |
| 9 | 30 | Maximilian Seesslen | |
| 10 | 60 | Maximilian Seesslen | STM32 with SD-Card slot and quite big Flash. No RTC is not cool. |
| 11 | 35 | Maximilian Seesslen | (PC should not collect data poe-a-poe.) |
| 12 | 1 | Maximilian Seesslen | |
| 13 | 12 | Maximilian Seesslen | * CAN |
| 14 | * UART |
||
| 15 | * (Q)SPI |
||
| 16 | * RTC |
||
| 17 | 11 | Maximilian Seesslen | |
| 18 | 45 | Maximilian Seesslen | Why not just using CANDIs? check flash. |
| 19 | |||
| 20 | 1 | Maximilian Seesslen | h2. MCU |
| 21 | 2 | Maximilian Seesslen | |
| 22 | 53 | Maximilian Seesslen | h3. STM32L443CCU6 |
| 23 | 3 | Maximilian Seesslen | |
| 24 | CAN/USB Multiplexer vom CANDis uebernehmen. |
||
| 25 | 16 | Maximilian Seesslen | Das Package hat kein SDMMC interface. |
| 26 | Also hoellischen viel QSPI-Flash drauf. |
||
| 27 | 6 | Maximilian Seesslen | USB-Detect vom minutnik-eink testen. |
| 28 | 1 | Maximilian Seesslen | Bischen unterfordert. |
| 29 | 6 | Maximilian Seesslen | Flash: |
| 30 | Ich hab doch mal 1,8V flash gekauft. |
||
| 31 | CS ist auch bei QSPI noch vorhanden. |
||
| 32 | 1 | Maximilian Seesslen | Da reicht ja ein stm32f042 ... |
| 33 | |||
| 34 | 53 | Maximilian Seesslen | h3. STM32F303C6U6A |
| 35 | |||
| 36 | 1 | Maximilian Seesslen | Good old "STM32F303C6U6A"; ist klein (QFNP32), hat kein VBAT. |
| 37 | STM32F103C6U6A sieht gut aus. VBAT. USB und CAN geht nicht gleichzeitig, ist aber verdrahtbar. Laeuft nicht mit 1V8. The RTC is strange, although it works. |
||
| 38 | 16 | Maximilian Seesslen | |
| 39 | Doch gleich nen STM32L431CBT6, dann gibts auch QSPI. Und die 4 Stueck sind dann auch gleich weg. |
||
| 40 | Und sie koennen 1V8, VBat ist da. 1V8 fuer RTC wird aber tricky, oder ich versuch mal nen Elko/supercap |
||
| 41 | 1 | Maximilian Seesslen | Sowohl via USB als auch via CAN power-bar. Dann braucht man nicht zwangslaeufig CAN am PC. |
| 42 | Hat kein USB. |
||
| 43 | |||
| 44 | 53 | Maximilian Seesslen | h3. STM32L562ZET6Q |
| 45 | 1 | Maximilian Seesslen | |
| 46 | 53 | Maximilian Seesslen | verfuegbar; LQFP-144 noch alberner. |
| 47 | |||
| 48 | h3. STM32L443CCU6 |
||
| 49 | |||
| 50 | 24 | Maximilian Seesslen | VDDUSB: 3.0-3.6V when USB us used; 0V when CAN is used |
| 51 | 32 | Maximilian Seesslen | An level-shifter for UART. Only making it in USB-Mode makes it impossible to test CAN. |

| 55 | 49 | Maximilian Seesslen | Cool, even CAN bootloader; |
| 56 | 32 | Maximilian Seesslen | But no SDMMC for 48pin package. |
| 57 | 51 | Maximilian Seesslen | |
| 58 | 1 | Maximilian Seesslen | h3. STM32L431RCT6 |
| 59 | 51 | Maximilian Seesslen | |
| 60 | 57 | Maximilian Seesslen | "Datasheet":https://www.st.com/resource/en/datasheet/stm32l431rc.pdf |
| 61 | |||
| 62 | 1 | Maximilian Seesslen | LQFP64 |
| 63 | 61 | Maximilian Seesslen | Kein USB. But with SD-Card it makes sense to have and "CANRec", without USB. I can connect the SD-Card directly to computer, no USB for device necessary. |
| 64 | 1 | Maximilian Seesslen | *Current choice* |
| 65 | 61 | Maximilian Seesslen | |
| 66 | 50 | Maximilian Seesslen | |
| 67 | 44 | Maximilian Seesslen | h2. Bootloader |
| 68 | 1 | Maximilian Seesslen | |
| 69 | 56 | Maximilian Seesslen | -PA11: USB DM line. Used in alternate push-pull, no pull mode.- |
| 70 | -PA12: USB DP line- |
||
| 71 | 1 | Maximilian Seesslen | |
| 72 | 59 | Maximilian Seesslen | CAN-Bootloader needs HSE; PB8/PB9 messes with SDMMC |
| 73 | 56 | Maximilian Seesslen | |
| 74 | 1 | Maximilian Seesslen | Uart would be nice, why is PA9/PA10 not working? Not blocking anything. Make it "predefined" and see what will fail. |
| 75 | 59 | Maximilian Seesslen | I2C: want PB10, PB11; should be possible when using PA2/PA3 for QUADSPI -NCS/CLK |
| 76 | |||
| 77 | 40 | Maximilian Seesslen | |
| 78 | 17 | Maximilian Seesslen | h2. RTC |
| 79 | |||
| 80 | 18 | Maximilian Seesslen | Supercapacitors have an discharge of 1μA. They wont feed RTC for more than a day. |
| 81 | Battery with shottky should do the job. |
||
| 82 | 19 | Maximilian Seesslen | |
| 83 | 1 | Maximilian Seesslen | RTC-Mode: 200nA; Battery with 20mAh |
| 84 | (20000000/200)/ 24 / 365 = ca 11Jahre. |
||
| 85 | 25 | Maximilian Seesslen | |
| 86 | 1 | Maximilian Seesslen | Use same battery like in Schiebleere. |
| 87 | 39 | Maximilian Seesslen | Hope that VBAT can be > VDD. |
| 88 | VBAT: 1.55V ... 3.6V -> need 3V |
||
| 89 | 25 | Maximilian Seesslen | |
| 90 | 46 | Maximilian Seesslen | h2. Display |
| 91 | |||
| 92 | QSPI: |
||
| 93 | RVT43ULBNWC03: 72.77Euro; 4,3``; BLVDD: 3.6V-5V |
||
| 94 | 47 | Maximilian Seesslen | "Controller-Doku":https://brtchip.com/wp-content/uploads/Support/Documentation/Programming_Guides/ICs/EVE/BRT_AN_033_BT81X_Series_Programming_Guide.pdf |
| 95 | |||
| 96 | Memory-mapped QSPI-Flash along with display could be tricky. |
||
| 97 | An SPI display would be possible. But why an additional CANDis. |
||
| 98 | |||
| 99 | 1 | Maximilian Seesslen | CANDis laeuft ja noch nicht mal. Ein andermal. |
| 100 | 48 | Maximilian Seesslen | I want RGB-Interface. |
| 101 | 46 | Maximilian Seesslen | |
| 102 | 55 | Maximilian Seesslen | h2. Onboard sensors |
| 103 | |||
| 104 | The extern I2C-Bus is for cool sensors. |
||
| 105 | An cheap lm75-temperature sensor could be on board. |
||
| 106 | |||
| 107 | 21 | Maximilian Seesslen | h2. What else to do |
| 108 | |||
| 109 | 27 | Maximilian Seesslen | CANBridge mit aufnehmen? Dann isses nicht mehr 1V8. |
| 110 | 22 | Maximilian Seesslen | Nur Batterie, Flash und CAN-Anschluss sind a bisserl mau. |
| 111 | 28 | Maximilian Seesslen | USB/CAN-Mux, ok. |
| 112 | SAI gibts gerade nichts. IR auch etwas Sinnlos. |
||
| 113 | 26 | Maximilian Seesslen | |
| 114 | 1 | Maximilian Seesslen | I2C for the temperature sensor. |
| 115 | 27 | Maximilian Seesslen | |
| 116 | 60 | Maximilian Seesslen | * I2C ext. 2, 2 connectors |
| 117 | 33 | Maximilian Seesslen | * I2C int. 2 |
| 118 | 27 | Maximilian Seesslen | * RTC 3 |
| 119 | * CAN 2 |
||
| 120 | 54 | Maximilian Seesslen | * -Switch- |
| 121 | * -USB (switched)- |
||
| 122 | 1 | Maximilian Seesslen | * QSPI (Flash) 5, record data |
| 123 | 54 | Maximilian Seesslen | * SPI (Flash) 5, config, firmware-update, fallback fuer nicht funktionierendes QSPI |
| 124 | * SDMMC |
||
| 125 | 1 | Maximilian Seesslen | * Uart 2 |
| 126 | 54 | Maximilian Seesslen | * -USB-Detect- |
| 127 | 28 | Maximilian Seesslen | * 2 mal LED |
| 128 | * Debug 4 pins |
||
| 129 | 54 | Maximilian Seesslen | * Buttons brauchts gar net |
| 130 | 28 | Maximilian Seesslen | |
