Hello everybody I am using the on-chip flash programmer in CCS 3.3 to program a F2812. After clicking execute program in the on-chip flash programmer window, first it started working normally but at the beginning of the erasing procedure it stopped. I waited for a long but there was no progress in that procedure. I decided to close the on-chip flash programmer window, reset the board and unplug ...

Hi, I am a new user of F2812 (and also in your forum) and I face problems with QEP using simulink. I am trying to check through RTDX if my QEP input is right before implementing any advanced control code. Firstly, when QEP and PWM are in the same EV then the captured results are inconsistent. Contrarily, in different EVs everything seems to work perfectly (almost). Secondly, the encoder r...

Hi, I am using F2812 chip to implement the following. 1- Generate a symmetric three phase PWM, PWM7-12, using EVB on chip. 2- Map the compare match 4, CMP4, to call a software Interrupt service routine using PIE. The first task, PWM generation, was successfully done. I have verified the physical hardware output using a scope. However, for the second part, compare match Interrupt, I couldn?t

Hi all, I have bought a few DSP - TMS320F2810 from a broker. When opening the flash utility, the flash is password locked. When the password addresses in flash memory((0x3F7FF8 - 0x3F7FFF)) verified, it shows all zeros. This means that, the DSPs are already locked. But without knowing the password, it can never be unlocked, using JTAG emulator. Does , anybody know , some other metho...
