Hello,I have not found the maximum TRACECLK frequency of the STM32H725 in the documentation. It looks like it is generated by PLL1 with flexible division ratios and thus can attain values that are not realistic for I/Os (100 to 220 MHz for Speed 11 a...
Hello, I am reading 6.3.30 LCD-TFT controller (LTDC) section to interface with DS90C385A (LCD) or ADV7125 (VGA) Assume that LCD Clock (pixel clock) polarity is set to high. Ideally, we can expect rising edge of clock aligned to the middle of the data...
Hello, How to perform dual-core communication on STM32H747?
There is this errata for STM32G0B12.2.10 Prefetch failure when branching across flash memory banksDescriptionIn rare cases, the code prefetch may fail upon branching and function calls across flash memory banks,regardless of the DUAL_BANK and nSWAP_B...
I have seen that it takes about 28 ticks to read registers, so I think my stm32h750 runs really at 17Mhz, it seems is not risk, so perhaps it exists another more fast stm32 micro that have more 17 MIPS
This is a pretty basic question but I would like a bit of clarity if possible.If a GPIO pin is configured for the fsbl code can it also be used in the Appli code?If so how would you go about defining it in the Appli code? There doesn't seem to be an ...
Our company has a chip that outputs data via DCMI, though it does not employ a standard DCMI interface. It lacks a horizontal synchronisation signal, possessing only a vertical synchronisation signal. Could you advise which chips are capable of recei...
Hi,I have a custom board with an STM32L031C6 and I'm trying to read the internal temperature. The board is battery powered at about 2.6V and the vdda is the same.If I read the ADC channel with vrefint, it returns a value of about 850, which, when pas...
Hello,I configured TIM1 as shown in the attached image: Everything works as expected I am controlling an inductive load which oscillates heavily after the PWM is turned off. I therefore decided to immediately short the low-side MOSFET (CH1N) to groun...
Hello ST Support Team,I'm working with the STM32L031K6U6 (32-pin UFQFPN package) and need clarification on ADC channel mapping.Question: Is there an ADC Channel 9 available on the STM32L031K6U6, and if so, which physical pin does it map to?Context:- ...
