Posted on July 05, 2012 at 18:59Hi Everyone,I'm writing a program that receives data from the USB and writes data into the flash. The program also resides in flash.Before each erase and write operation, the USB is NACKed because the flash erase/writ...
Posted on July 03, 2012 at 09:55I've just purchased ST-Link/2 programmer and installed ST-Link Utility v.2.3.0. I load intel hex file which contains 0x55, 0xAA at adressess 0x0800FFFE and 0x0800FFFF respectively. The device is STM32F103C8T6. Howeve...
Posted on July 05, 2012 at 01:52Hello.I'm facing a problem when trying to send data with function USART_SendData(USART1, (uint16_t)resultat) (resultat is a int 32 bits).When i step by step debugged it, i discovered that my program just enters in an ...
Posted on July 01, 2012 at 13:32 Hi, everyone. I'm testing on fsmc stm32f407VG. I use the Address / Data multiplexed on databus (MUXEN = 1). 2 modes of testing EXTMOD = 0 and 1. Initialization: FSMC_Bank1->BTCR[0] = //FSMC_BCR2_EXTMOD | ...
Posted on July 01, 2012 at 13:57Hi, everyone. Testing STM32F407. Runs it at 168 MHz (5.92 ns cycle), FLASH-> ACR = FLASH_ACR_DCEN | FLASH_ACR_ICEN | FLASH_ACR_PRFTEN | FLASH_ACR_LATENCY_5WS. Outstanding at the PA1 a simple square wave: PM_(RCC->AHB...
Posted on July 04, 2012 at 10:38Hi,i have IAR KickStart Kit for STM32F107VC and i use some code for Ethernet and its running well, it can send the UDP packet and receive it, now i want to see the recived packet so i am trying to send all the incomin...
