I think the problem is deciphering the Opcodes for the SPI for the dataflash and all the address bits and dummy bits that need to be sent. Very little changes were needed to the code and the Debug told me the errors ? I am using ATmega8535 and AT45DB161B Configure the STK500 Programmer Support in the CodeVisionAVR IDE by selecting: SettingsProgrammer AVR Chip Programmer Type: STK500 + corresponding communication port 5.
Codevisionavr codes pdf#
The version of the C code I used was from the PDF application note, the code was on the last pages.The following code is in the corner of the pages. I seem to be able to write some of the data to the buffers in dataflash but if I switch off and on again it does not appear to be saved in flash memory pages. I tried to test this by trying to send text data into RS232 port, save this to dataflash and read it back out again. I think it is not writing the correct values to Dataflash. The most popular versions among the program users are 3.4, 3.3 and 3.0.
Codevisionavr codes software#
The most frequent installer filenames for the software are: cvavr.exe, cvavr.ir.exe, cvavr1.exe, cvavr.exe and cvavretc. I have got AVR335 Digital Sound Recorder going, compiled on AVR Studio AVR GCC Winavr I changed the code to suit Studio and all works except the PWM output is very noisey. The tool can also be called 'CodeVisionAVR Evaluation', 'CodeVisionAVR Beta 5', 'CodeVisionAVR ATM18 Evaluation'. PORTB |= 0x08 // turn LED off while running idle
