The basic PSoC 5 Timer functionality is as follows: the counter register starts at the “period”.

#PSOC SOFTWARE FULL#

interrupt a signal that tc, capture or fifo full has occurred.

tc (Terminal Count) a signal when the terminal count is reach (aka 0).

capture_out (signal when a capture event has occurred).

reset (an active high to reset the whole block).

enable (an active high to turn on counting).

capture (a signal to capture the current count).

trigger (a signal to start counting – either rising or falling edge).capture fifo (a place to store the counter value when a capture event occurs).period (a register which holds the value to put back into the counter when the 0 is reached).

#PSOC SOFTWARE 32 BIT#

counter (a 8,16,24 or 32 bit register that is used to count input clock pulses).

There are Registers (inside of the block), Inputs (which can be triggered by signals on the chip) and Outputs (which can give indications to the rest of the system that something happened) This can give you ability to have more timers than are natively supported by the chip.Īll three of the timers work the same basic way.

#PSOC SOFTWARE CODE#

The UDB based timer is synthesized from RTL, Datapath and Code into the Universal Digital block which exits in all three of the PSoCs 3/4/5. The two fixed-function timers (TCPWM and “Fixed Function” are implemented as hard blocks in the silicon of PSoC3/5 and PSoC4 (TCPWM) which saves silicon area.

“TCPWM” in PSoC4 (Timer, Counter, Pulse-Width Modulator)Īll of these blocks have the same basic functionality but have slightly different implementations (and customizers and APIs).

“UDB” timer in PSoC 3, 4 & 5 (Universal Digital Block).

In the PSoC Family there are 3 basic timers that we provide: You can find all of these project on the IoT Expert GitHub Cypress PSoC 5 Timer

Suggest other things that could be done, and point out a few errors/improvements in my projects.

Show a modification using a PWM to display the output.

Show a modification using a PWM to test.

Explain the debugging process of my software project.Explain a minimally changed software based solution.Show the problems in the original implementation.Explain the Cypress PSoC 5 Timer functionality.I thought, “OK, that makes good sense, we will do that”.

I can easily do this on an Arduino using pin change interrupts but I wanted to implement this on a PSOC so I decided to use the timer component”. The original email says “ I am simply trying to measure the pulse width of a signal that ranges from 1 to 2ms. RC, thats wireless right? that counts as IoT, right :-)? This article doesn’t really have much to do with IoT, except that the engineer who sent me the problem originally is using an RC servo motor remote control (I think). I explained my problem and literally 10 seconds later he gave me a good fix, which I implemented and then sent off to the customer. So, I called my PSoC secret weapon, specifically, the bad-ass engineer Greg. Finally at 3:08 (yes exactly 3:08) I stopped because there was one part of my solution that I didnt like. Sunday around noon I posted a couple of working projects to the forum… but… and there is always a but … I didn’t really like the answer so I kept working on it. I always like using PSoC 5, so I looked at it for a while (until my wife started yelling at me about working), then right before bed, I sent him a short statement of the cause and told him that I would send the project on Sunday. He had already posted on the Cypress forum and did not have functional answer. Then, after dinner I checked my email for where I found an email from a customer in California who was having a problem with a PSoC 5 Timer. I spent all day Saturday working on the firmware for the next post in my series of articles about PSoC4 BLE Centrals.
