Hi All,I am trying to impliment a frequency shift keying (FSK) routine to represent a each bit of a byte as FSK.My routine is kind of working (see the IRQ for TIM3 below). My FSK is :Bit 0 & Start : 3600Hz Bit 1 & Stop : 1200HzThis ensures that timin...
We are currently working on a project using the STM32H750IBT6 microcontroller interfaced with a single-bank Quad SPI NOR Flash (MT25QL512ABB) on our custom board. The QSPI interface is operational.However, we are facing an issue with the external loa...
All,I have somehow concocted a CubeMX configuration (attached) that causes the CPU to latch up when the LTDC clock is enabled during HAL initialization. Here's what I'm seeing/doing:Debugger loads flash, breakpoints at HAL_Init() in main().Set a bre...
Hi, I´m beginner in SMT32 MCU design, I´m doing a design for the above MCU and in the document "AN4555" that is for hardware develoment of these MCU series I founf that So for my package (64 pins) the VREF and the VDDA power signals are bounded insid...
Core : STM32H743Z , STM32H753V, STM32H750 @ 480MHzExternal Sync Clock (as EXTI0): 10MhzI tried to read/write GPIO ports with TIM2_UP and TIM3_UP events, in sync with an external clock. Data transfer (both in and out) is taking place, but not synchro...
I have build the SNK1M1 project directly from github. For some reason it is missing PDOs. As a result there are several things I am not capable of doing.Any idea why this is not showing PDOs in the STM32CubeMonitor panel?Next to VDM SOP there should ...
Hello. I configured the USB port on CubeMX and the generated code compiles with error usbd_cdc_if.h: No such file or directoryI seem to only google arduino references to this file ??Any clues gratefully accepted.
I'm trying to configure the STM32H7S3L8 to work with a 24-bit parallel RGB LCD. From what I've read, this kind of interface usually requires either an LTDC peripheral or a dedicated display controller board. However, I can't find any documentation co...
Hi AllI have a digital power converter topology (H-bridge) which requires waveform to look like the following:As can be seen in the above, complementary waveform is being sent on bottom 2 channel in 1st 10ms and then they are being in the IDLE state ...
Hello All,While working on a design i was stuck in a point where in i have to map PSRAM pins --> FMC_clk on a port of MCU(STM32N647A0) which is available on PC10 but it is conflicting with SPI3_SCK.Please anyone can suggest solution on this. My desig...
