h1. Eval
Relatively big MCU; Standard periphery can be tested within a single bringup run. Protocol can be added to biwak/arena release.
Current use-case:
* I2C has an issue that some times the board has to wait at bootup quite long time till i2c eeprom is functional.
* SPI has an issue that some times the board has to wait at bootup quite long time till spi flash is functional.
* Code cleanup; does the code still work; e.g. Timers. Complete disfunctionality would not be seen some times.
* Want to develop something with nice debug output. Bootloader was a little bit nasty.
No further use?
* Alarm clock
* CANBuzzer
* Reference RTC clock
** CANSwitches have PWM output but no RTC. For light switches this compination makes sense. CANDis could do this. At least in combination with buzzers nice.
STM32L433CCU6; 48pins; 256KB Flash; "DS":https://www.st.com/resource/en/datasheet/stm32l433cc.pdf
* CAN
* USB
* Uart
* SPI-Flash
* I2C-EEPROM; 80Bytes + ?KB
* I2C-Connector
* Buzzer
* LEDs
* Small LCD? waste of pins?
* RTC
* PWM-LED; Golden Dragon?
* ADC (fixed resistors; 1/4 VDD)
* Button
PA11 - CAN1_RX USB_DM
PA12 - CAN1_TX USB_DP
PB8 - CAN1_RX
PB9 - CAN1_TX
Power-Cut would be a killer feature. But without companion?
