PSoC™ 4 Forum Discussions

I download CapSense  code example, i compile the project , but  can not open the ELF file  using uc/probe, it shows error as picture below, how to solve this problem? thanks.

After building and compiling the program, the green led started blinking when I pushed switch 2 and the motor didin´t run.

I already measured all the voltages in the board and it seems that they are ok.

Could somebody help me!!

Hi, I am using the IDAC of a PSOC 4. What is the temperature drift of the current? Is it the same tolerance as the reference voltage?

Hello,

I have used  the following example program provided with the PSoC Pioneer Kit and the CY8CKIT-037 PSoC4 Motor Control Evaluation Kit to rotate a Stepper Motor in both CW and CCW directions. I intend to use this to introduce the basic principles of Stepper Motor Control in an educational setting. Therefore, I would like to have some inputs on how this program can be modified from Microstep to simple FULL STEP. I would like to retain the provision for Start/Run  and speed control which is currently available using the SW2 and the Potentiometer ( Variable resistor R38). Appreciate help from the Cypress community.

The ADC_SAR_seq Input resistance is specified as 2.2K Ohm max. Is this a series Resistance of the SAR_ADC path or the overall input impedance of the SAR_ADC?

The low input impedance ADC will limit the application and may require the OP-AMP buffer in the front end.

How do I change the name that is shown in Cysmart from Unknown, I started with the IAS example, and the "find me" service has a name, but I cannot find in settings or code how it got its name so I can name my services and not have 7 unknowns, unless you dig down to the descriptor.

MY BLE services, the immediate alert is displayed as "Find Me" in Cysmart, all others appear as Unknown, WHY and how do I change them to their names?

Odd question (and I've got more debugging to do):

I've got 3 development boards. Basic HeartRate Sensor example runs great on 2 of the 3 boards. On the 3rd board, I get dumped into the IntDefaultHandler at the BLE_Start() call. Stepping through the code, the offending call (again, on only 1 set of the hardware) is CyBle_StackInit().

Breakpoint at the first/initial return to the Handler (CYBLE_EVT_STACK_ON) never hits.

Further complicating this is, I can fire some simple code with just digital I/O, timers, and UARTs and it will run flawlessly (into the offending hardware).  Any big brain, experienced ideas out there on what can/could be going wrong w/n the PSoC4 on the 1 set of hardware that is fine on the other 2?

Physical inspection of the pins doesn't show anything obvious, but I'm thinking that this could just be a bad part? Or part that maybe got ESD'd during placement on the board? Anyone seen that happen.

where can I get a definitive list of the assembly language instructions supported by PSoC 4. the TRM specifies some that GCC AS rejects

I am using the following documents
