STM32F405 Multiple ADC multiple channels DMA problem
Hi all, I am desperately trying to sample 15 ADC channels using the 3 ADCs of the F405.First I tried using the multi ADC triple mode, with 5 channels set for each ADC. I used DMA to transfer data to memory. It seems to work, but I get garbage data in...
Unable to retrieve data from STM 32 board using pyserial
In this code, when I use the temp command, I always get output as "No response received." That means my python CLI is not receiving any data from the STM 32 board. But when I run the same command on the screen terminal on my mac, I get the data. What...
Resolved! STM32G0 transition from Run Mode to LP Sleep Mode
Hello, the STM32G0 low-power state diagram (Figure 8 below) is in the ref. manual RM0444 on page 127.It shows that a direct transition from Run Mode to LP Sleep Mode is not possible.Questions:* Is there a simple method to transition from Run Mode to ...
Resolved! OSPI skipping bytes
We have been using an STM32 U585 with additional external FLASH connected to OSPI1 and external PSRAM connected to OSPI2. This is not on a dev kit, it is our own hardware. The PSRAM is memory-mapped and is using the HyperBus protocol. We have noti...
STM32C031C6 I2C error handling
I am using STM32C031C6 MCU connected to an NTAG5 IC via I²C. The MCU is configured as an I²C master transmitter and master receiver. Polling mode is used to transmit and receive data to/from the NTAG5.Below is the code I am using to write and read I²...
Resolved! STM32H7S78 USB CoreReset timeout
Hey All, Similar issue to this previous topic,I'm running into a timeout error every time I try and call USBx->GRSTCTL |= USB_OTG_GRSTCTL_CSRST from the USB_CoreReset function in the example code. It seems like the previous solution was to make sure...
Resolved! STM32H753 QSPI Status Flag Polling fails with Instruction on 4 lines
Hello,I stumbled across a probably already wellknown problem:unable-to-use-quadspi-status-flag-polling-mode-with-instruction Now I'd like to know if there are any news, somebody wrote that the issue is observed by ST.Second I'd like to know if newer ...
Resolved! Error in initializing ST-LINK device. Reason: No device found on target.
Hi everyone, I'm having trouble writing my program to my microcontroller, and I'm hoping someone can help.When I tried to write my program in STM32CUBEIDE, I received the following message:STMicroelectronics ST-LINK GDB server. Version 7.8.0 Copyrig...
How to configure GPDMA for PWM generation?
Hi,I'm using a Riverdi RVT50HQSFWN00 Screen with the STM32U5A9NJH6Q MCU. COnnected to pin PI0 is a WS2812 LED light strip. I already configured the timer 5 channel 4 for PWM generation and validated it with a scope at the pin. Right now I'm stuck at ...
