PSoC™ 4 Forum Discussions

Hi.

My customer use PSoC 4100S Plus.

I understand that the raw count is adjusted by 85% (+/- 10%) when the IDAC is autocalibrated.

When the resolution is 12 bits, it is recognized as within the range of 3067 (4090 x 0.75) to 3885 (4090 x 0.95).

However, it may fall below or exceed 3067-3885.

I have not touched the sensor.

What could be the cause?

Best Regards.

Hi all,

      I use PSOC Creator 4.3 create a demo project for 4147AZS-S475, and system clock settings as blow,

I can use PSOC Creator 4.3 debug the demo, it's OK. Then I export the demo to IAR, but IAR debugging is failed. Errors occur while initialize system clock, if codes enable EXCO, the debug is failed.The code is shown blow,

      It's so strange, if I download code to chip using IAR, it can run well. But I can't using IAR debug the code.

      While debug failed, IAR shows CPU status FAILED,

     I guess, IAR can't connect to MCU when enable EXCO. How can I fix the error..

Best Regards

Hi，

If can I modify macro definition in header file?

Such as #define CapSense_CSD_RAWCOUNT_CAL_LEVEL       (85u)  in Capsense_configuration.h

If I changed 85 to 60 ,when project was built,the value would recover to 85.

So,we couldn't modify macro definition in header file,is it?

Thanks!

I am using two CYBLE-222014-01 modules, one as peripheral and other as central. Once the central finds the peripheral, it goes into sleep mode but maintains the link to the peripheral. The central device automatically wakes up at some interval and must check the connection to keep the two linked. The central device can also be woken up via interrupts from two switches. The problem I am having is randomly and under no pattern, the link between the two devices is broken. The peripheral sensed the break and begins advertising again, however, the central device still thinks the two are connected even though I check the state when every time it wakes up., no flags are set in the stack that it disconnected. Forces the central to be power cycled to work again and start scanning. Open to ideas as to what is wrong or if a better way to detect link is broken.

I also can't find much information regarding setting the scan interval settings in the GAP Setting tab of module configuration. All Cyrpess datasheets focus on module as peripheral not central device. Any documentation on proper settings for scanning, not advertising. How to match to peripheral side?

My customer wants to design a PSoC in IAR.

Is there a manual or sample for the design flow of IAR (not use PSoC Creator)?

Especially, I want to know how to set up SmartIO.

Or, should I ask the IAR directly?

Thanks,

Hi everyone,

I know there is a way to change the ID of a TX mailbox during runtime. I was wondering if there is a way to do the same for RX mailbox? My use case:

I have a bunch of MCU's networking over can. These MCU's have dipswitch's that correlate to a CAN ID. During runtime, I would like to initialze by doing the following:

1) read dipswitches to get CAN ID

2) set teh RX mailbox CAN ID so we only interrupt the MCU if there is a message on the network with its CAN ID.

I've looked up and down the data sheet, and even looked at the CAN_RX_CFG struct but there does not seem to be a parameter for rxid.

Thanks in advance!

Hi,I use the command (IDAC_SetValue(0xFF) ) to set the value to 0xFF,but I actually measure the voltage of R1 as 4.5V and current is 220uA by multimeter.

Anyone knows where I set it wrong?

Hello

I want to use CAN communication with PSoC4100S Plus.

I want sample code and design guide.

i want to build a program in which i am taking a psoc module 4, a gsm modem and pc..tilll now i used pc to coomunicate with gsm modem, but now i want my my micro controller  to communicate with gsm modem with no intervention of pc.. i want to write AT on putty software and through which that at goes into micro controller and then from micro controller to gsm modem.. so my GSM answers OK which goes to microcontroller and then to pc.

so i want to basically use microcontroller as a tunnel in betweeen.. and want to develop a serial communication between micro controller and gsm.
