Posted on January 02, 2014 at 06:01Hi All, I'm having problems with getting my 2Gb Micro SD card to initialize. From deubgging, I have found the problem occurs in the FindSCR(RCA, scr) function called within SDEnWideBus(FunctionalState NewState). Sp...
Posted on January 03, 2014 at 03:17 EDIT: Solved by clive1! See post below. Hi (again), I'm tinkering with Interrupts this week. I'n the example code I have provided below, The Green light flashes (as expected) in the loop....
Posted on January 02, 2014 at 18:26Hello everyone. I probably have some usual problem about i2c communication. Namely, I have the following code and trying to read MPU6050 WHO_AM_I register(http://www.invensense.com/mems/gyro/mpu6050.html). The addr...
Posted on January 01, 2014 at 01:49Guys, Can I use MAX485 and STM32F107VCT6? I can't find VH max on F107 datasheet, is it possible if I interface MAX485 with STM32F107VCT6 USART ? pin PA9 and PA10 connected directly to MAX485 Any clues ? Thanks #...

Posted on January 01, 2014 at 15:11 Hello Friends, Using STM32F103RB how can it be done: --->>RS232(RX Recieve Message)---(Process Message)--CANBUS(Transmit Meesage)---> Wait for response(interrupt, poll vs.)...--->CANBUS(Recieve Meesage) --(Proces...
Posted on August 22, 2012 at 17:29In STANDBY mode my board current drops to 300uA which is as expected. However if I use STOP mode it is 880uA. I had expected STOP mode to be only 20 - 30 uA more than STANBY. In STOP mode I turn all pins to analog i...
Posted on December 25, 2012 at 14:43Hello all,I created my own breakout board for the STM32F405RGT6, but I'm unable to connect to it via the ST Link V2. The error is ''No Target Connected''.I've tested this with an external 8Mhz crystal (with load c...
Posted on December 31, 2012 at 19:28Dears, I have problem while debuging the code for STM32L151RDT6. I get every time the hard fault exception with bus fault. Description of Project: I am using KEIL 4.54 with ST Link/V2. The system has SPI FLash (8M...
Posted on December 31, 2012 at 16:49I will use the STM32 to drive a power supply. The input signals to the ADC do not need any gain, so I'd like to avoid using as many OPAmps as possible. The problem is that many of the potentials are negative or ...
