I've been trying for hours to read an analog value from a pin and write it over UART with no success on my STM32MP1. I've assigned PF14 to ADC2_INN2 and set IN2 to "IN2 Differential", then I generate the code and when I try to build I get a bunch of errors with regards ...
When I just add ADC init function into main.c, error L6218E appears.linking...\Objects\charger_stm32f0.axf: Error: L6218E: Undefined symbol HAL_ADC_ConfigChannel (referred from main.o)..\Objects\charger_stm32f0.axf: Error: L6218E: Undefined symbol HAL_ADC_Init (refe...

最终发现把 MX_DCMI_Init();放到 MX_DMA_Init();即可正常传输数据 Several peripheral DMA handle pointers point to the same DMA handle. Be aware that there is only one channel to perform all the requested DMAs.干扰项,删掉就行不用管,我开始还以为这里需要配置什么东西,就保留最上边一行 ...

44.2.2 ADC时钟源选择 ADC有两种时钟源可供选择,可以使用来自AHB总线的系统时钟(属于同步时钟,对应下面框图的adc_hclk),也可以使用PLL2,PLL3,HSE,HSI或者CSI时钟(属于异步时钟,对应下面框图的adc_ker_ck)。 结合上面的框图,ADC的时钟源要注意以下几个问题: ...

断言功能:HAL 库函数执行时,会使用assert_param(expr)进行参数检查,仅当USE_FULL_ASSERT时有效,若断言失败,则会调用由用户实现的assert_failed传递断言失败的位置;该功能应该是用于DEBUG的。 2.2 HAL 初始化与 Msp_Init 若使用 HAL 库进行开发,则必须要在main函数最前面调用HAL_Init进行 HAL 库的初始化 ...
