Hello,
Iam using CY8CKIT-042-BLE with CY8C4247LQI module with UART to BLE example project. When I send over UART a long message (about 40 bytes) it sends it in 3 messages over the Bluetooth. My problem is that there is a delay between these messages about 100 ms.. Send 40 bytes message then takes about 200ms. Is there a way how to increase the speed of the communication? Thanks
Show LessI tried to change the modes of the ADC via firmware.
code:
void SetADCMode (enum sar_mode mode) {
uint32 reg_sar, reg_sample;
reg_sar = CY_GET_REG32 (CYREG_SAR_CTRL);
reg_sar & = ~ 0x00000EF0;
reg_sample = CY_GET_REG32 (CYREG_SAR_SAMPLE_CTRL);
reg_sample & = ~ 0x00000004;
switch (mode) {
case vref: //
reg_sar | = 0x000002C0;
reg_sample | = 0x00000004;
break;
case vref2:
reg_sar | = 0x00000EC0;
break;
case vdda:
reg_sar | = 0x00000270;
reg_sample | = 0x00000004;
break;
}
CY_SET_REG32 (CYREG_SAR_CTRL, reg_sar);
CY_SET_REG32 (CYREG_SAR_SAMPLE_CTRL, reg_sample);
CyDelay (5);
}
And I received false readings ADC.The project is built with the ADC configuration as shown in Figure 1.

Hello Everybody!
Creator suggests using a control file for making it fit my project into four UDBs. When using the suggested lines, nothing changes. Please see my Forum-entry "Unable to pack the design into 4 UDBs - Control file doesn't help form 3rd of August. Thanks!
Show LessA new Beta version of RSVP (Reference System Virtual Platform) has been released for PSoC4/CY8CKIT-049 at :
https://github.com/rsvpsis/rsvpsis/tree/master/rsvpsis/brds_lib/Cypress/CY8CKIT-049
RSVP includes a fully populated project with UART, I2C, ADC, DAC, etc.
components already wired up and ready for your application.
RSVP is an easy way for new users to start with a working project
that includes the most used components along wth a IPMI compliant metadata store,
command line interface, and many other features.
best regards,

Hello,
I'm trying to measure a capacitive 'button' that changes by around 10pF between no-touch and full-contact scenarios. I would like to be able to quantify intermediate values as well (so being able to measure 25%, 50% or 75% of full-contact by reading capacitance values between the no-touch and the touch limits).
My issue is that I would like to use the SmartSense to do this because the manual settings seem to be less reliable; however, I can't get a large enough range in SmartSense mode. Even with the sensitivity at 10, I easily saturate the sensor when changing from no-touch to touch.
Is there any way to lower the sensitivity (increase the range) even more in the SmartSense mode? I would like to have the full-contact at around 80% of the max sensor value (around 200 for 8-bit sensor).
Thanks,
Dillon
Show LessI see that in the iOS and Android apps, I can perform an OTA update. Using the example project I can connect to the device and I see the bootloader service then I am given the option to "Select upgrade option" this takes me to a page "Select Firmware Upgrade files". This is an empty page.... How do I load a file (both iOS and Android)
Thank you in advance for your help!!
Show LessIs there a way to write to a txt file or something through UART? I tried to just use fopen, fwrite etc. But the file isn't created and it gives the error "function not implemented".
Show LessI am PSoC4 beginner, so I am a little confusing about ECO. When I read PSoC4 datasheet and it explain XTAL24I can input 24-MHz crystal or external clock input. But a diagram in the datasheet show crystal is only connected at XTAL24I pin. Therefore, I suspect if I can input external clock signal into XTAL24I pin.
Please tell me whether I can connect external clock signal into XTAL24I pin or not.
Thank you.
Show LessI designed a new pcb for the azi 48 pin tqfp version. Ordered some chips from cypress store, but they haven't shipped yet.
Has anyone already got some and would be willing to sell and ship 1 or 2 to me in knoxville tn asap?
Thanx,
Ed
