Logbook of the commissioning of the first board

LEDs

The LEDs work as expected.

They are turned on via:

  HAL_GPIO_WritePin(LED4_GPIO_Port, LED4_Pin, GPIO_PIN_RESET);

and switched off by:

  HAL_GPIO_WritePin(LED4_GPIO_Port, LED4_Pin, GPIO_PIN_SET);

LEDs

The LEDs are visible, but rather dim. So decreasing the resistance from 2k2 to 1k2 might be a good idea in order to increase visibility.

D1 = red D2 = yellow D3 = yellow D4 = green

USART

The USART is working at 115200.

CAN Bus

CAN Bus working, both RX and TX.

Note:
for RX the CAN filter must be set. There are two FIFOs, which can be handled via an interrupt.

ADC

Getting the timer into operation.
Channel 4: Output Compare No Output Mode: Toggle on Output

ADC is triggered on Timer 4 Capture Compare 4

Quite helpful:

PWM

Works 512 = 1.65V 1024 = 3.3V

ADC is now running continuously, and gives about 16 000 samples per second of all inputs.

First board was quite successful, some issues found, which are going to be fixed in revision 2.0. See #11 for commissioning of the new revision.
