I am trying to read 2 channel ADC with STM32L011F4.My ADC and DMA settings in cubemx are as follows my problem is that the DMA only returns the low 8 bit of the last channel.uint16_t ADC_Reads[2] = {0}; while (1) { HAL_ADC_Start_DMA(&hadc,(uint...
Hi, I am trying to make a circuit with stm32f103c8t6 and a nrf24l0+. I attach my schematic if pcb layout needed tell me to upload that. One of the circuit work good ( the send one) the other one which is identical does not.after soldering I did check...
Various STM32 products have opamps that have a mux in front of it.Ex: STM32G4, STM32F3, STM32H7 series, etc.If I change the mux input setting using the control status register (OPAMPx_CSR::VP_SEL or VN_SEL), how long does it take for the mux to switc...
Hello Community,I've B-U585I-IOT02A. I got this with pre installed web-server with react client. Whenever I was connecting it with terminal like tera term or minicom. It ask for configuring the wifi after successful configuration, it start the simple...

How far from FMC shall we place memory device. I have stack-up design(3 boards) in which MCU is on top board and FPGA is on bottom board. I need to map FPGA to FMC. Are there design consideration for routing FMC signals for such board to board commun...
Hello, I'm trying to set up an interrupt when my FDCAN controller received a CAN message. MCU is an STM32G01BI went into STCubeMX and I enabled these interrupts:This generated some new functions instm32g0xx_it.c:void TIM16_FDCAN_IT0_IRQHandler(void) ...
I'm following the P2P template example and I found that to send data using BLE, the example uses the Custom_STM_App_Update_Char function. However, as I know the update API is aci_gatt_update_char_value. So, I'm confused because the Custom_STM_App_Upd...
I have a reading problem with dmaWhen reading multi channel with ADC dma I need to know when to sample each channel. In the ADC input, I found a 2us transient in the oscilloscope output below. I considered this transient as adc sampling time and adju...
