Hi
I am trying to perform a simple test code for PGA900 in order to make sure that the program can be executed by my ideal.
So, I added program in PGA900_cfg.c making pin 27 and 26 of PGA900 in high level, which it is convenient me to use a voltage meter to detect. the programming as follow:
#if (TEST_CPU_RUNNING == 1)
/* GPIO1 and GPIO2 are outputs, push-pull */
GPIO_Config(GPIO1_OUTPUT_PUSH_PULL | GPIO2_OUTPUT_PUSH_PULL);
/* Put value '1' on GPIO2, make GPIO2 as high */
GPIO1_HIGH();
GPIO2_HIGH();
#endif
then, the program was compiled CCS 6.1, and produced a HEX file without any error message.
I follow the user manual of "PGA900 Pressure and Temperature Sensor Signal Conditioner" in chapter 2.5.2.10.3 DEVRAM Programming to load the HEX file to memory until the progress bar to 100%, but I didn't see high level in PGA900EVM TP22(GPIO2) and TP18(GPIO1).
Did I have to do something after loaded the HEX file to trigger the chip running?
Thanks
