Posted on July 16, 2014 at 20:12Hello All, I was trying to write and read data from SDRAM on the STM32f429- Discovery board.I was able to write data to the SDRAM but the read operation was not working.I used the STM32Cube Mx utility to generate the ...
Posted on July 31, 2014 at 00:05 Hello! Setup:2 custom boards (1 that's similar to the Discovery F4 and one that's based on a PSoC 5LP) linked by RS-485 (SN65HVD75 transceivers, half duplex, single twisted pair). Data flow: the STM...
Posted on July 31, 2014 at 05:05 The interrupt handler is generated by CubeMx in another file. Here is the code, no changes were made to it: /** * @brief This function handles EXTI Line 0 and Line 1 interrupt. */ void EXTI0_1_IRQH...
Posted on July 28, 2014 at 16:12Hello,I'd like to use an USB example project on a different (but very similar) microcontroller on a custom board.The example project: STM32 USB FS Device Library V4.0.0 --> VirtualComport_Loopback project --> STM3210B...
Posted on July 30, 2014 at 10:35Hi, to unlock data EEPROM on STM32 I need to write a sequence of two values to the FLASH_PEKEYR. Any failure in the sequence will permanently lock the EEPROM. Now there are some questions: - Do I need to disable inter...
Posted on July 29, 2014 at 21:40Hi, I am using STM32F103R8T6.I normally perform the in-circuit programming using the STMFlashLoader.exeSometimes I need to erase and program some pages performing an In-Application programming. I use the library funct...
Posted on July 29, 2014 at 18:45Hi I am working fora project withthestm32ldiscoverybutI have a problem:the Delay functionthatI implementedin my programis not working void Delay(uint32_t nTime) { TimingDelay = nTime; while (TimingDelay != 0); }void T...
Posted on July 28, 2014 at 11:46Hi everyone, I have to design an IIR Filter and i want to use the DSP library provided. I'm new to digital filtering and i want some help to understand the biquad function in the library. I found an exemple in the arm...
Posted on July 30, 2014 at 10:23Hello Is it possible to differ a reset caused by a POR/PDR from one caused by a BOR? The flag PORRSTF gets set by a PDR as well as by a BOR. I need to check if power voltage dropped only below VBOR or also below VPOR....
Posted on July 29, 2014 at 08:36 Hi, I am trying to sent some data to the controller (STM32F051) via pl2303 connector. Data is sent from an application. The problem is, I'm not able to receive the data sent by the application properly. The d...
