Hi,this is my MCU code: STM32H563VGT6. I'm working to a porting from Texas to ST.I need to efficently use the two Rx FIFO (3 messages depth) of the FDCAN module. In Texas I had 32 mailbox divided into transmission and reception.Each FIFO has four buf...
Hello, i need help with na stm32l031k6, I want to just start the processor and read it with an st-link v2, I have connected BOOT0 to GND(i haven't added a 10k resistor, but that shouldn't be the problem ), NRST with pull-up 1k to VDD, VDDA and VDD ar...
I am starting some test with this modulehttps://it.aliexpress.com/item/1005002482177244.htmlwith 7” lcdI have found only one example that run but with TouchgfxI have got the same ioc from this example to generate a new code and insert the functions t...
I am trying to persuade an stm32F412 to provide Periodic PC sample packets.Reference manual RM0402 implies it is doable (Configure DWT as a PC sampler)The "Cortex-M4 Technical Reference Manual r0p0" says "You can configure the DWT to generate PC samp...
Hi, For a reason that I cannot explain, the STM32U575ZI (on the nucleo board) is sending a CAN bus message with infinite repeats and 100% bus utilisation, but I have repeated transmission turned off (DAR bit set to 1) and I have confirmed this using ...
Hello everyone,I am developing a custom PCB and am having a problem while trying to flash the chip.Before delving further, I need to say that I have made a mistake with routing the JTAG traces to 10pin JTAG connector and may have burnt the chip. I tr...
Hello,The setup comprises a keyboard connected to the Host-configured USB port of an STM32F4 dev board and the keyboard is configured with the following two HID Report Descriptors: 0x05, 0x01, // Usage Page (Generic Desktop Ctrls) 0x09, 0x06, ...
I'm searching for super coding comfort in CubeIDE. Currently TIM2 resets/updates.In HAL_TIM_PeriodElapsedCallback() I "manually" start HAL_ADC_Start_DMA() the Scan conversion of four channels and have the four results shipped into my progs memory,...
