The problem is a complier error because in the cube MX (version 4.20.0)
for the STM32F373R8Txusing ADC1 (12 bits ADC) I can choose, in the configuration tab,ADC1 and as external trigger source for regular conversion the TIM4 CC4 event....
this will generate this code:
....
hadc1.Instance = ADC1; hadc1.Init.ScanConvMode = ADC_SCAN_ENABLE; hadc1.Init.ContinuousConvMode = DISABLE; hadc1.Init.DiscontinuousConvMode = ENABLE; hadc1.Init.NbrOfDiscConversion = 8; hadc1.Init.ExternalTrigConv = ADC_EXTERNALTRIGCONV_T4_CC4; <-- compiling this will generate an undefined error ! hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc1.Init.NbrOfConversion = 8;....in the HAL libary header (version 1.7.0 lates up to date) stm32f3xx_hal_adc_ex.h
at the line 1349 there is: &sharpdefine ADC_EXTERNALTRIGCONV_T4_CC2 ADC_EXTERNALTRIG_T4_CC2at the line 1827 there is: &sharpdefine ADC_EXTERNALTRIG_T4_CC2 ((uint32_t)(ADC_CR2_EXTSEL_2 | ADC_CR2_EXTSEL_0))Reading at the manual STM32F37xx Reference Manual (RM0313) in the chapter 12.12.3 ADC control register 2 (ADC_CR2) the documentation report:
......
EXTSEL[2:0] External event selector for regular group:the value (bits) 101 that is (ADC_CR2_EXTSEL_2 | ADC_CR2_EXTSEL_0)
the manual reports that with this configuration the trigger source should be TIM4 CC4 Event.
.....
is there anybody that can explain this ?
Thank you very much in advance for your help !
