Resolved! STM32G474 Flash wait states at 170MHz CPU clock
RM0440 Rev 3 (last version) recomend to set 4WS for 170MHz CPU clockRM0440 Rev 2 recomend to set 8WS for 170MHz CPU clockST driver library (STM32G4xx_HAL_Driver) function LL_PLL_ConfigSystemClock_HSE() set 8WS for 170Mhz clock. Which Flash WS setting...
Resolved! Project migration from STM32F405RG to STM32G473RE
STM32G4 CPU speed. I am migrating a project from the STM32F405RG to the STM32G473RE. System clock frequency for both is 168MHz. I have found the code runs at about half speed on the STM32G473 and I would like to know why and how to fix it.The STM32G4...
STM32L471 ADC1 unstable calibration and accuracy at 80Mhz. Stable at 40Mhz.
Hello,I'm working on a project involving the STM32L471 device clocked at 80Mhz (Externalcrystal oscillator with internal PLL).We are using ADC1, also clocked at 80Mhz (CKMODE = 0x01)We are noticing an issue concerning the calibration (and the consequ...
Resolved! Not understanding IWDG and HAL in STM32F7
Hi, I am trying to get working IWDG using HAL_IWDG library and I am not able to refresh the watchdog before IWDG_Reset. As is said in page 6: (https://www.st.com/content/ccc/resource/training/technical/product_training/group0/01/24/22/29/38/70/40/57/...
Resolved! The behavior of the gpio pin when powering on and powering off
This question may applied to the whole STM family and maybe pure hardware related, but I expect someone can give some clues.May I safely assume the gpio pins are high impedance when powering on?If I set pin to output, and output a high. Then, the p...
Uart baud rate never seems to be enough to transmit the 30fps received from ov7670
Hi, any reply is greatly appreciated. I intend to interface ov7670 with my nucleo board for a qvga with yuv422. To get 30 frames per second ,the pclk must be set to 24Mhz(according to the data sheet). What this means is that each byte is received fro...
Is It Possible to Change BOOT0 pin of STM32G071RB ?
Hi, I looking for BOOT0 pin from the NUCLEO-G071RB. I want to change the boot configuration then turn the BOOT0 pin to HIGH. So, I could reach the system memory boot. But, the errata sheet says that Under Level 1 read protection, booting from Main Fl...
Resolved! Does STM32F730V8 support SDRAM or not?
It says specifically in datasheet that it does, but when I create new STM32CubeIDE project and select STM32F730V8, FMC only offers PSRAM/NOR Flash/LCD interface. I tried for testing purposes selecting some other MCU that also supposedly supports SDRA...
Resolved! STM32F407 discovery board. Basic Timer TIM6 and Interrupt to toggle LED without HAL driver
HiI am trying to better understand the registers and register manipulation to set up the following scenario:Toggle LED on PD12 every 1 second via TIM6 and Interrupt Handler.Below is my code. I enter the interrupt service routine (verified by setting ...
