I conducted an experiment with the following settings and results: LTDC - 0x20020000 (Internal RAM), Display - 0x20020000 (SDRAM): Display output is visible.LTDC - 0xC0000000 (SDRAM), Display - 0xC0000000 (SDRAM): No display output.LTDC - 0xC0000000 ...
Hello, I was testing f103 in a standby mode and wiring a nRESET line was enough to connect to the chip with a Segger debug probe in a connect under reset mode. But apparently L0 chips also require pulling BOOT0 pin high. I am guessing that is beca...
I have been simulating errors on the bus by removing the other node (a motor controller). As expected I see a number of failed transmissions. I can see that the FDCAN peripheral signals an Active Error on the bus (presumably as a result of not gettin...
Hello -Board - STM32 NUCLEO-L476GPeripheral board ADXL313 (16 byte data registers)Interface - SPII can perform single byte read, combine the 2, 8 bit values and the data is correct. Yet, when I try to perform a 2 byte SPI read, it's garbage. This wo...
Hi everyone,I started a project a few weeks ago, which for reasons of urgency I had to use a black pill board as an initial prototype, using STM32F401CCU6 (of uncertain origin). The project continued to develop almost completely until we assembled th...
I'm using the STM32G431CBU3 in a project that shares the same ground for digital and analog supplies, but the UFQFPN-48 package doesn't have a VSSA pin like the others. What should I do in this situation? Should I consider VREF as my VSSA?
Posted on October 19, 2013 at 05:31I'm new to the ST product line. While reading the datasheet for the STM32F051 I came across the following in section 3.5.1 ''Power supply schemes'':The VDDA voltage must always be greater or equal to the VDD volta...
Hi, have any of you communicated with a display based on the ST7735S controller? Based on this library: https://github.com/afiskon/stm32-st7735 I converted it from SPI communication to 8080 parallel control, but display does not work properly, while...
Hi,where do you set programmatically (perhaps through a preprocessor directive) the option to lock the micro to prevent read/download of the flashed code but while obviously still allow for firmware updates?Also I could not seem to find any such opti...
Hello, i am trying to use system bootloader in STM32F411 for software update via USB. I use a freertos in my project.Workflow is here: By sending a "BOOT" via Virtual Com Port USB, MCU executes folowing code: SpoilerUSBD_Stop(&hUsbDeviceFS);uint32_t ...
