Other Parts Discussed in Thread: CC2640
Good afternoon, I made one small board with CC2640R2FRSMR (4x4mm) this has only 10 GPIO, I follow this reference:
CC2650EM-4XS-RD reference design | TI.com
the schematic to develop the PCB, and this AN to setup "External Regulator Mode" 1.8V:
Using the Wireless SimpleLink CC26xx in External Regulator Mode With the TPS62740 (ti.com)
before execute BLE, I take one code example NoRTOS from simplelink_cc2640r2_sdk_5_30_00_03,
The code example is: "gpiointerrupt", I change the code and setup pins in CC2640_LAUNCHXL.h
to blink only GPIO9, unfortunately it didn't works.
1. My desigb PCB the oscillator 24MHz, has two CAP of 15pF each, the code example not works.
2. I have removed the CAP bez the chip has cap compensation, not works.
I hope someone can help me.
