Hello - Does anyone know of a Gcode interepreter for the STM32L4. I am building a 6 axis robotic arm and want to use my nucleo board (with L4 series) to control the motors. I have put alot of time and effort in finding gcode interpreter but haven't f...
Hi all, I'm discovering 32-bit microcontrollers for the first time. My project is almost completely working (using Timer 1 in input capture mode and all the rest is GPIO related). I want to save one variable so that it survives power down. Because th...
Hello all, I have encountered unexpected behavior on the voltage level of PC12 when I enable PB12.My setup:PC12: Level high, output mode PP, no PU no PD, Output speed High. PB12: Level low, output mode PP, no PU no PD, Output speed Low.Without PB12 t...
Hello, I've an error in the interrupt but I don't see where it can come from.
I have developped a graphical demo with the STM32H735 discovery kit, and the minimum frequency of the OCTOSPI to have a clean display is 66 MHz (framebuffer = 480x272x32). Now I want to use in my application an External RAM with QUADSPI (framebuffer...
Hello there, recently i have found a error in the application note an4839.The strongly-ordered memory region in the Table 2. Memory region shareability and cache policies is remarked as non-schareable. Howerver according to ARM DUI 0646B ARM Cortex-M...
Hello, has anyone ever used UART to read arrow key? I tried using STM32 MCU on CubeIDE, but can only get two characters ASCII number 27 and 91 and couldn't get the third character which is supposed to be 'A' for Up key, 'B' for Down key, 'C' for righ...
I have some projects that were left inadvertently with some function calls that write 0x00 bytes into the data EEPROM. They work properly. I have tested it.I detected the problem on a prototype board with an old sample of STM32L152C6T6 and this made ...
I am using STM32h753XI.The MCU uses 2 SPI channels (SPI1 and SPI2) in slave receive mode.The MCU uses 2 DMAs channels (DMA1 stream0 and DMA2 stream0) to read the data from SPI1 and SPI2 and write it to SRAM1 and SRAM2 respectively.The input SPI sclk ...
