Part Number: TMS320F28020 Other Parts Discussed in Thread: C2000WARE Hi All,
Current project needs sw reset feature. Previous iteration (microchip MCU) used a GPIO pin to pull its own reset pin low. This approach hasn't worked with the 28020. First…
Part Number: TMS320F28020 Other Parts Discussed in Thread: C2000WARE Hi All,
I'm back with more questions about setting up the SCI BAUD rate.
In the last episode, I was getting irrational BAUD rates due to the fact that I had the SYSCLK running at…
Hi Lori,
It looks like we'll move forward using only floating point operations, and abandon IQ Math. It may arise later if I need to do any more serious filtering (like adding biquads, etc.), but for now floating point operations suffice.

Part Number: TMS320F28020 Other Parts Discussed in Thread: C2000WARE , TMS320F28027 Hi All,
The math to set up I2C and SCI clock rates hasn't been working quite right. When I select a value, the data rates are a little higher than anticipated. I just…
Part Number: TMS320F28020 Other Parts Discussed in Thread: C2000WARE Hi All,
Using CCS 10.4, I'm adding I2C functionality to a project that started as the TIREX example, "Example_2802xScia_FFDLB.c", shown here:

Part Number: TMS320F28020 Other Parts Discussed in Thread: C2000WARE Hi All,
I'm looking for some advice on a good way to implement the SCI module to receive messages ranging from 10 to 20 bytes. I acknowledge the need for a parsing routine to discern…
Part Number: TMS320F28020 Hi All,
I'm laying out a PCB that has a TMS320F28020 on-board and would like to provide an interface for programming/debugging with an Olimex TMS320-XDS100v3.
Mapping out signals has been pretty straightforward, but I'm not…
Thanks Matthew,
Vddio noise is about 540mVp-p riding on 3.3Vdc. At its lowest point, it reaches down to 3.06V, which is still within the 10% tolerance. Although, the documentation says that BOR tolerance is 5% when the on-board Vreg is enabled.
I switched…
