Hello..I am using STM32F429 Disco Board in which I am trying to interface finger print sensor NB65210 of next biometric using spi and I need to read the finger print data I have a example code in which it is reading properly but it is not reading whe...
Hi I want to understand "which register decides whether HSI or HSE oscillator is selected for PLL clock source in STM32F407"(selection of the HSI or HSE oscillator as PLL clock source"B.RAsh
Dear All,I would like to interface an ADC (ADS131M08) with a STM32F407. The ADC datasheet mentions that for better performance, the ADC clock should be synchronized with the SPI clock. Is there any way to achieve such synchronization with the STM? I ...
Hello ST, 1. ds12736 Rev.4 states in Table 24 that the abs. max. voltage on any pin is at least +4.0V (but this may be further limited by an injection current limitation) 2. ds12736 Rev.4 states in Note 4 on p.145: "Positive injection (when VIN > VDD...
Hello, this is DK.I am working on a project using stm32f429IIt6.I'm currently having an I2C problem at the end of my project.I2C1 uses PF 0, 1 / I2C2 uses PB 6, 7. The HW PCB completed, and the HW I2C pull up is the same.In I2C1 HAL code, the entire ...
Hi I am using STM32F407 I want to make IRQ handler for busOff inetrrupt so can I use CAN1_SCE for bus OFF interrupt? B.R Ash
Hello. I have a problem, I wanted to test the power saving mode on a board with a microcontroller stm32h743vit6. For this, I made a minimal project. Where I switch to stop mode and wake up by pressing the button. Consumption in this mode is about 4.5...
Hi,STM32H533 datasheet (DS14539 Rev 2) in table 88 says that RDY input setup and hold time are both 0.5ns. From my naive point of view it looks like superb value (RDY have to be stable only +-0.5ns around CLK edge). Isn't that a typo ? (STM32H7 PSSIs...
The FDCAN module generates timestamps for sent and received messages, and you can configure it to use TIM3 as the source. Unfortunately, the documentation is rather thin, so I am left with a few questions:Do TIM3 and FDCAN need to run from the same c...
Hi, i'm developing a board with 7" lcd (LVDS) so i'm really hesitating about if is right to use a SN65DSI83 for this, my STM32F469IIT6 only have 2 DSI Lanes. I'm connecting the i2c lane from SN65DSI83 to i2c of STM, i just copied the circuit of cm4-b...
