Hello,I'm using the STM32N657 processor and have the HEXASPI device running at 1.8V. VDDIO2 is connected to 1V8 supply (which affects: PO[5..0] and PP[15..0]The FMC is placing the A23 line on pin PO1 (this is the only option for the FMC-A23) and the...
I drew a board of stm32h503rbt6, including a screen and a NOR flash. The flash model is mxl6433f. Currently, the problem I'm facing is that when I try to program the board using stprogram, I encounter an error that the programming cannot be completed...
Heyho,strange things happening that I'd like to understand for a STM32L073 (Nucleo for now).Setup on a L073 @ 32MHz:- ADC is clocked by PCLK/4- ADC prescaler = 2 -> divide by 4 -> 2 MHz- 12 bit right aligned- ref V = VDDA = 3.3V- hardware oversamplin...
Hello! I am working on a custom OTA bootloader system on a STM32G473RBT6 MCU in a custom board I have been using maybe for 3 years with no problem. My board is connected to a Raspberry Pi over RS485 network. My idea is this:There are 3 virtual sectio...
Hey everyone,I’ve been using the STM32F429IGT6 for an audio project, and I'm running into an issue with the ADC readings. When the system is idle, everything seems fine, but once the load increases, the readings start to fluctuate unexpectedly—partic...
Hi,I would like to recreate the DCMIPP_ContinuousMode example but using the cubeMX to configure the MCU, I haven't found anything online to follow as example.Thanks.
Hey together, I have a question regarding changing the clock while running in XiP mode. Upfront everything works so far very well. On our STM32H750 we have a very simple bootloader. This bootloader configures the QSPI and the STM32H7 to run the appli...
Hi everyone, I’m working with a custom made STM32F446ZET6 board that otherwise functions perfectly (all peripherals, flash programming, etc. work fine). The only thing that doesn’t is the ROM bootloader. I can’t get USB DFU or UART boot to respond no...
Hi,I'm exploring using UART idle interrupt on RX to signal to my application that data has arrived.I currently push data into a tx queue then start transmission. I rely on uart tx ISRs to check if there is any more data to send, then load up a DMA tr...
I am trying to use one STM32M4 as TX, and another STM32M4 as RX,but RX can't receive the correct i2s data that TX transmits.TX transmits 16bits data by HAL_I2S_Transmit_IT(&hi2s2, i2s_dummy_buffer, 16);RX receives 16bits data by HAL_I2S_Receive_DMA(&...
