Hello guys good day. I would like to ask for your suggestions regarding the UART interrupt between 2 STM32F103C8 MCUs. I can transmit and receive between 2 MCUs using a single input and output with the use of the IRQHandler. However when I wanted ...
Hello,i am trying to use the virtual comport of the stm32f407vgt6 to communicate with my win 10 pc. I want to send 16 bytes of data. I created a base project in cubeMX and insert the cdc_transmit. There it is possible to send 16 bytes of data via the...
Hello,i want to communicate with an AD7998, to convert 8 analog to digital channels. The communication i use is I2C. I am using the HAL library.According to the adc manual i need a repeated start, after writing to the address pointer byte. So i had ...
For 24-bit I2S, should the data/memory alignment be configured to a word because it's 24-bit data on a 32-bit frame, or should it be configured to a half-word because SPIx_DR is a 16-bit register?
HelloI have a hw configuration that uses mpu6050, lora chip, gps, and bluetooth using stm32f103 mcu. I use lithium polymer 3.7v 1300mah for power to board.It doesn't make sense to me, but it's like this.After downloading the firmware via stlink, mpu6...
It is configures as same baud rate as my embedded board and PCAN GUI is running. When I run program I see Tx error counter is incremented and no frames are sent out. When refereed to LEC it is bit dominant error.Bits 6:4 LEC[2:0]: Last error code10...
FMC bank 1 is set to NOR Flash PSRAM, bank 3 is set to NAND Flash. The transfer of NAND flash uses DMA.MPU of the above regions are set to non-cacheable, non-buffable, non-shareable.The issue occurs when PSRAM read happens during NAND flash read. The...
I 'm using this board for CAN communication with CAN1. I notice in User manual UM1871 Figure 14. MCU 1 CAN1_TX is connected via SB18 and it is open. For CAN1_RX it is mentioned in user manual that I have to close for Rx to work and not mentioned abou...
I am trying to use ADC with 2 channels and DMA, but I only get 1 reading before the overrun bit gets set. Also the 1 reading is wrong, I am expecting a value of approx 2100, but I am getting around 70. I can see in the hadc->DR that the value are cor...
Hi !i'm trying to write a driver, to interface the "ADS1220" device with STM32F103RBT6, using SPI,i would like to assign each pin of the MCU SPI (PA4, PA5, PA6, PA7) with its corresponding pin of ADS1220 like this : using macros#define ADS_CS PA4 // ...
