I downloaded v10.72D of DC and installed it. In the previous version of 10.72 I have (I don't know what letter version it is),I am using function I2C_initClk() found in I2C_HW.LIB to switch between a 200kHz clock and a 400kHz clock. But thatfunction is not there in v10.72D. Is there another mechanism provided to do the same thing that I'm not seeing? Steve

We do embedded software, but the hardware is produced by our customer (we don't control it). Sometimes we need to attach a wire (for monitoring a serial or I2C interface, or for timing instrumentation) to a surface-mount IC where the pins are VERY close together. The pins are so close together that I can't solder a wire to it, even using high-power optics and the finest soldering i


Macro CC_REV

For DC v10.72, how is macro CC_REV defined?  Is the value going to be 1072D, _1072_D_, etc. I need to know what to test for. Steve

Hi Folks- FreeRTOS has a build config file (FreeRTOSConfig.h) that users can apply at build time to customize the RTOS. The FreeRTOS web site has a page to describe the options (https://www.freertos.org/a00110.html). What it doesn't have is any hints about how much RAM it might save me. Does anybody have any first hand advice about how much RAM each option might contribute to the R...

Has anyone had any experience using the erc802-1 series of serial (i2c) lcd modules ? I have not yet succeeded with getting mine to display anything and any suggestions would be most welcome. This is what I am doing - I am using the power-on reset with the reset input wired to +5v. In software I wait for about 50ms after switch on, then execute code which produces the clock (yellow) and dat...

Select option -> Generate Code -> Build -> Build fails. Select different option -> Generate Code -> Build -> Build fails. Try yet another option -> Generate Code -> Build -> Build fails. Harmony is a giant framework where you select from hundreds of options (drivers, TCP stack, etc), then generate your application's frame. It favors a monster-loop state machine, at a point where the applica
