I am using STM32U083 MCU in a project that runs on a 3.6v Li-SOCL2 lithium thionyl chloride battery (OC voltage 3.65V / Nominal voltage at 1mA 3.6V).Currently I have used a LDO of 2.5v to power the MCU, but I was thinking if we can eliminate the LDO ...
So i'm following along with this video* https://www.youtube.com/watch?v=usQ_f6Swpok&list=PLTJzs51NlEICI7ARAHOyUqMhTgJE0UFv0&index=5 I have the same* STM32N6-DK board This is my build command for the GPIO_IO_Toggle application.* /opt/st/stm32cubeide_1...
Hey!I will explain my setup and then paste the code. I have three different timers (TIM1, TIM2, TIM3) sending out PWMs to different parts of my board. All timers are set up the same way; the only difference is that TIM1 is an advanced timer.What I do...
Hello,I am implementing SPI master communication on an STM32G474RE, transferring 68 bytes per transaction. However, I am unable to achieve the desired SPI clock speed of 5 MHz—currently the SPI clock only reaches approximately 3 MHz.The system clock ...
On a stm32u5, the SPI3 is in the SmartRun domain, which is designed to work down to STOP2 in autonomous peripheral mode with LPDMA. I'm now wondering if it is also possible to use SPI3 in autonomous mode with GPDMA but only to STOP1? Or do I need to ...
Hi Team, Could you please assist me with the following situation: CANFD is working with FIFO0, but not with FIFO1, same config, using STM32G0B1KEU6. I am using same channel, FDCAN1. I will attach both files for refference. Thank you in advance, A...
Hi, I am trying to reset HRTIM on an external event using TIM1 TRGO as a reset event. I am trying to make a single pulse every 200ms (5Hz) because I want to make a single puls test. However, I also need a high resolution so I can vary the on time and...
Hello ST Expert, On our custom board - USB PD, it has 1. HW: TCPP03-M20 with STM32G0B1CBT6 2. SW: X-CUBE-TCPP 4.2.0 ( USBPD Application 4.2.0 - Dual_Role) 3. SW: Board Part tcpp0203 1.2.3 4. Tools: STM32CubeMX (6.15) & STM32CubeIDE 1.19.0 & STM32Cub...
Hi, I am using an STM32H755XIH6 MCU in a custom design. I want to use only LDO supply configuration for the internal power regulator that provides the VCORE and I don't really intend to use the SMPS configuration. My schematic has some hardware mista...
Hello, Can I say that "IDLE" is equivalent to "RTO with 8-10 bits (depending on framing)"?Or are there some other subtle differences? My goal is to transfer received data with DMA and start interpretation of the data when nothing is received on the l...
