Hello All, I am trying to do a loopback test between 2 i2c's on the same board, using bare metal coding and interrupts, and the clk is HSI, 16MHz. How the i2c i configured as slave is failing to acknowledge the address sent by master i2c.Here is a zi...
Hello everyone,I have designed a custom PCB using STM32F103RBT6 and I’m facing a serious issue:The MCU is not getting detected by the programmer.Symptom:When connecting via SWDIO, SWCLK, 3.3 V, and GND, both STM32CubeProgrammer and ST‑Link Utility fa...
Hi there,I tried to add support for a PDM microphone, but so far I could only get 0's from DMA. Somehow, the polling method (HAL_SAI_Receive) did return non-zero values. Here is how I set up the SAI and DMA:I did so by modifying our project's existin...
I'm trying to set up CAN communication between two STM32F4 boards using CJMCU-230 transceivers, but I'm not receiving any messages. Here's a full breakdown of the setup and what I've tried:Hardware Setup:MCU: STM32F4 Discovery (hcan1)Transceiver: CJM...
Hi all,I am working on a project involving reading from the external AD7768. I've tested to get data out of it using and EXTI and Interrupt based SPI receives, but that was too slow to capture the message, so I'm trying to get it to work with DMA.The...
Hello, We have designed custom board using STM32F412VGH6 and have implemented a custom bootloader to support firmware upgrade.A common debug UART is shared between the bootloader and application firmware. The UART pins are configured as follows:->TX:...
I am very new to this field !! So last I had posted regarding the interfacing of DCMI and I got relevent doucuments which where not enough for me to understand the DCMI module. So could you please send relevant videos of interfacing DCMI module step ...
I am trying to make a very simple program that will initialize Si4703 and read data out of it, the manufacturer ID or something.And in the datasheet, it says to initialize the chip, I need to have SDIO turned low on the rising edge of the RST pin.Si4...
Hello,I'm here on H75x. I'm looking for portable way to do a timeout check via timer.Here, I want a timeout IRQ if UART receive DMA hangs up.First I setup a OnePulse timer in Cube. It generates the following code:if (HAL_TIM_Base_Init(&htim6) != HAL_...
I want to the RTC to my project, but something is preventing the RTC clock from being enabled and I can't figure out what it is. IOC file is attached.
