Hi, I need help for estore coupon. I got an email the redeem free board with exclusive code on ST estore. After applying the code, A message "Your cart is not eligible for this promotion. Ensure that you are logged in and items match promotion ter...
First time designing for ST microcontrollers, so I thank you for your patience. I see by the datasheet that USART1 can be used as a LIN bus directly without a LIN bus transceiver, but I can't find any examples of how the hardware is implemented when ...
Regarding LL_AHB1_GRP1_EnableClock, after setting bit in the function, it is read to "tmprg" and cast to void type. What is the reason for reading?__STATIC_INLINE void LL_AHB1_GRP1_EnableClock(uint32_t Periphs){ __IO uint32_t tmpreg; SET_BIT(RCC->AHB...
Hi I'm trying to understand something in the schematic the disco1 IM pins are set to 4-wire 8-bit serial IIn the picture below they are connected using the SB22-25 but I've checked the board and they are not soldered so it is not possible to set the...
Heyho,until now I only used STM32 with the LAN8742, in a few weeks I'll get my 2nd custom board, but this time with the "dual" PHY KSZ8863RLL.It's connected via RMII, for setup MDIO (and optionally I2C for the registers not accessible via MDIO).Are t...
The new revision of errata sheet for STM32H7 mentions a new error relative to SPI: It is particularly vague.What "fast software" and "slow SPI" frequency means exactly ? What is the minimum ration between both frequencies to avoid the issue ?What "ad...
Using stm32G474RE nucleo board and following this guide, i know my way around old "advanced" Timers from stm, im just getting started with HRTIMChanging PER register has effect in the PWM frecuency, but changing CMP1 doesnt do anything :(Im not able ...
Hi!Does anyone know if there is a chance there will be a launch of a one-chip-solution for any of these MCU-series during 2025?What I mean is an MCU with large built-in FLASH + RAM preferably with a LQFP100/144-package (like the U5-series).We are pro...
Good morning everyone,I am considering buying a PSSI-compatible STM32. Beforehand, I would like to get in touch with some users who have already tried the interface out. I am considering PSSI to stream data out over 16 parallel lines at around 50-100...
Hello,I look at the STM32F103RB datasheet and see that this microcontroller should have 2 ADCs. When I open Table 5 (see Figure 1 below in this post) in this datasheet, I see only ADC12_IN10 and so on, that is, only ADC12. Why? ...
