Summary of change:
See CanBus The [https://shop.vems.hu/catalog/stm32f103mcp2515-p-213.html CAN Dash] was originally manufactured with STM32 microcontroller. The 25pin version is more featureful, with * more IO-s. HW has * 20+ analog inputs * temperature measurements * multiple frequency/speed inputs * and capable of input capacitive measurements for activation input buttons/switches Firmware utilizes some of these, with more possibilities in the future. ---- '''See CanBus, 3 different firmware versions:''' * BMW * VAG (Audi) * AIM see AimCanBusMessages (most data of these 3 versions) Uploading a different version (normally NOT necessary, if ordered with the desired version) takes only a few seconds. ---- '''Commands to upload''' Analog inputs: See AimToCanBusPinout '''DSUB25 male pinout (analog/digital inputs/outputs)''' * 1 - Analog 20 (with 5V pullup, PC4) * 2 - Rx * 3 - Analog 21 (5V pullup not populated by default, PC5) ** usable as 200mA '''low side output''' * 4 - '''GND''' * 5 - '''+5V (VCC in)''' * 6 - Analog 23 (PC7) * 7 - Analog 0 (PA0) Frequency/wheelspeed input_A * 8 - Analog 17 (PC1) * 9 - Analog 1 (PA1) Frequency/wheelspeed input_B * 10 - Analog 2 (PA2) * 11 - Analog 3 (PA3) * 12 - Analog 4 (PA4) * 13 - Analog 5 (PA5) * 14 - Tx * 15 - Analog 26 (with 5V pullup, PD2) * 16 - Analog 15 (with 5V pullup, PB7) * '''17 - Analog 14 (with 5V pullup, PB6) +17V input range''' * 18 - Analog 13 (with 5V pullup, PB5) * 19 - Analog 12 (PB4) * 20 - Analog 11 (PB3) * 21 - Analog 10 (PB2) * 22 - Analog 9 (PB1) * 23 - Analog 8 (PB0) * 24 - Analog 7 (PA7) * 25 - Analog 6 (PA6) ---- ADCMUX_ADC0_PA0, = > 0k ADCMUX_ADC1_PA1, = > 0k ADCMUX_ADC2_PA2, = > 0k ADCMUX_ADC3_PA3, = > 0k ADCMUX_ADC4_PA4, = > 0k ADCMUX_ADC5_PA5, = > 0k ADCMUX_ADC6_PA6, = > 0k ADCMUX_ADC7_PA7, = > 0k ADCMUX_ADC8_PB0, = > 0k ADCMUX_ADC9_PB1, = > 0k ADCMUX_ADC10_PB2, = > 0k ADCMUX_ADC11_PB3, = > 0k ADCMUX_ADC12_PB4, = > 0k ADCMUX_ADC13_PB5, = > 0k ADCMUX_ADC14_PB6, = > 0k (but lower readings, because of ) ADCMUX_ADC17_PC1, = > 0k ADCMUX_ADC20_PC4, = > 0k ADCMUX_ADC21_PC5, = > 0k ADCMUX_ADC23_PC7, = > 0k ADCMUX_ADC26_PD2 }; => !!
