Posted on May 22, 2013 at 16:47Hi Forum users, I try to bring in my project all the advantages that a TFT Display with touchscreen promises. The touchscreen controller STMPE610 with the Displaytech's TFT Display, DT028ATFT-TS, is used but unfortunat...
Posted on May 22, 2013 at 18:17Hi , Does anyone know about a free GCC toolchain that supports hardware floating point compile (FPU)? Because i am using Cortex M4F , and codesourcery lite does not support this feature. Thanks Michael #c-runtime
Posted on May 23, 2013 at 15:42hello forum I succesfully locked 0 my STM32F4 I want to know which ST document explains all of the lock bits ? thank you #stm32f4-lock-bits
Posted on May 23, 2013 at 12:31https://cmsis.arm.com/vendor/stmicroelectronics/ has the SVD that describes processor registers but it appears to be missing important things like the system control block that contains all of the fault information reg...
Posted on May 23, 2013 at 12:06 Hi togehter, I've some questions about the I2S interface of the STM32F405 microcontroller. I hope someone could help me I'm in a bit of a crisis here now. First to my hardware setup: I've the micr...
Posted on May 17, 2013 at 10:09HiWe are using STM32F373 for the first time in our units and a problem with SDADC full scale occurred. We use it in a simple resistor measurement circuit:Circuit compares Rx with a know Rref resistor. Controller is sup...
Posted on May 20, 2013 at 08:44 So I've been noticing recently that my stm32f4 discovery board is running under 168 MHz. Or at least I think. I'm trying to get this loop uint32_t i = 0; for (;i<76799;i++) { GPIOD->ODR = 0x4100; GPIOD->ODR...
Posted on May 05, 2013 at 00:45Hi again.I have made great strides in our system this past week (our first use of the stm32) and we have had great interest in this latest (stm32 based) product from potential customers and therefore we would like to s...
Posted on May 20, 2013 at 09:18Hello,I'm running my code on STM32F103 chip, I've set up a PWM output from timer1 with period of 200 ms, pulse width 5 ms, it's working and can be seen with a scope on GPIOA_8. The thing is, that I want to do something...
Posted on May 20, 2013 at 22:38I am using a STM32F407 and have set it up for using USART with DMA. I have some problems with the RX part. What is the best way to sync the enabling of the RX DMA with the remote transmitter? If I enable it in the midd...
