MCU & PSoC

Hey,

How do I add a custom font to the emwin library and GUI?

I have generated a .c file from a font using the Segger font converter. But I can't get it to work with the library. My setup is the CY8CKIT-062-WIFI-BT with a TFT display. The display works fine without the custom font.

Thank you,

Hello

I have used PSoC 4 and 5 and the APIs are very clear.

I am trying to use  PWM in PSOC6 (instance name PWM_1) and the functions available for say changing compare values are:

PWM_1_SetCompare0()

Cy_TCPWM_PWM_SetCompare0()

Which one to use? What's the difference?

Also, the PDL reference does not mention PWM_1_Start(), but it's available in the dropdown list when typing in functions. Where can I find the list of all APIs.

I am beginning with PSOC-6 but have used PSOC-4 and 5 for a long time.

Please help.

Thank you

I need to attach a sensor with an I2C interface to a CAN bus. What is the PSoC version with the smallest pin count that can be programmed with a CAN and I2C module?

Hello,

Hope you are doing well.

Actually i tried writing on SRAM of PSOC -4 BLE CYBL10162-56LQXI using the program provided by cypress (link- https://github.com/cypresssemiconductorco/PSoC-4-BLE/blob/master/100_Projects_in_100_Days/Day029_BLE_SFlash_Write/User%20SFlash%20Write.pdf.)

The program is getting loaded successfully on the device but when updating the SFLASH_STARTING_VALUE with different value for example (0xFF) instead of (0x00) its not getting updated.

Please refer to the screenshot below displaying only 00 even though we updated the value to (0xFF) in SFLASH_STARTING_VALUE instead of (0x00) in WriteUserSFlash.h header file.

Can anyone please help me in this as i need to write in SRAM of the PSOC-4 BLE CYBL10162-56LQXI device.

Thanks & Regards,

Hi,

I tried to use Cy_SMIF_MemWrite() with ModusToolbox and it always returned a timeout error.

I have QSPI FRAM configured for full QSPI operation.

The problem is in Cy_SMIF_MemCmdReadStatus() function as it only uses CY_SMIF_WIDTH_SINGLE for WIP flag reading.

I have modified the function and it now works correctly:

cy_en_smif_status_t Cy_SMIF_MemCmdReadStatus(SMIF_Type *base,
cy_stc_smif_mem_config_t const *memDevice,
uint8_t *status,
uint8_t command,
cy_stc_smif_context_t const *context)
{
cy_en_smif_status_t result = CY_SMIF_CMD_NOT_FOUND;

/* Read the memory status register */
result = Cy_SMIF_TransmitCommand( base, command, memDevice->deviceCfg->readStsRegWipCmd->cmdWidth,
NULL, CY_SMIF_CMD_WITHOUT_PARAM,
CY_SMIF_WIDTH_NA, memDevice->slaveSelect,
CY_SMIF_TX_NOT_LAST_BYTE, context);

if (CY_SMIF_SUCCESS == result)
{
result = Cy_SMIF_ReceiveDataBlocking( base, status,
CY_SMIF_READ_ONE_BYTE, memDevice->deviceCfg->readStsRegWipCmd->cmdWidth, context);
}

return(result);
}

Hi all,

I'm trying to use the two services CTS and ANCS, to update the clock and to receive notifications from iOS.

On event CY_BLE_EVT_GATTC_DISCOVERY_COMPLETE:

If I only call the function Cy_BLE_CTSC_SetCharacteristicDescriptor, it works

If I only call the function Cy_BLE_ANCSC_SetCharacteristicDescriptor, it works

if I call them both, the second returns the error 0x160002

what could be the mistake I make?

Thank you

Hi: I am using CY8CMBR3108 and, because the touch sensors become too sensitive after some time, I periodically send a RESET (CNTRL_CMD with 0xFF) command to it. However, for some reason (ESD?) I already had the situation that one (twice) or all (3 times) sensors of my product stopped working. The automatic RESET doesn't recover it. Only if I turn off the power and restart the unit, the sensors are back and all works.

After power-up I send the configuration that you see below in this post.

I find it very strange that, if after RESET (without power-off) I repeat the same configuration sequence (that is always performed after power-up), then no sensor is working. It is strange that the IC only accepts the configuration once after power-up!!!

The Power-up sequence is:

WriteToCs(SENSOR_EN, 0x001B, 2);
WriteToCs(FSS_EN, 0x0000, 2); 
WriteToCs(GPO_OUTPUT_STATE, 0x1B, 1); 
WriteToCs(BASE_THRESHOLD0, 200, 1);
WriteToCs(BASE_THRESHOLD1, 200, 1);
WriteToCs(FINGER_THRESHOLD2, 200, 1);
WriteToCs(FINGER_THRESHOLD4, 200, 1);
WriteToCs(DEVICE_CFG0, 0x00, 1);
WriteToCs(DEVICE_CFG2, 0x14, 1); 
WriteToCs(SENSITIVITY0, 0xCF, 1);
WriteToCs(SENSITIVITY1, 0x03, 1);
WriteToCs(REFRESH_CTRL, 1, 1);
WriteToCs(CTRL_CMD, 3, 1);
nack = 1;
Delay(C100_MS);
while (nack)
{
nack = CsdRead(CALC_CRC,buff,2);
Noop();
}
val = buff[1];
val <<= 8;
val += buff[0];
WriteToCs(CONFIG_CRC, val, 2);
WriteToCs(CTRL_CMD, 2, 1);
Delay(C100_MS);
nack = CsdRead(CTRL_CMD_STATUS, buff, 1);

Can somebody help?

Hello

I had tried HSSP using cy8c014LQI-422.

I'm stuck in DeviceAcquire() function.

I had compared my firmware waveform and cy3295 ttbridge waveform.

my firmware wave form shape is same but toggle frequency is 3 times slower than waveform of cy3295 ttbridge kit generate. 

Is there waveform timing diagram for HSSP?

I attached my project file.

Best Regards,

Sunghun noh

［質問内容］
UARTの FRAME ERRORについて
1.5ビット周期のストップビットシーケンスでは、ストップビットエラーを検出するということですが
1.5ビット周期のストップビットシーケンスでも、スタートビットでエラーが発生するのかを知りたいです。

ドキュメントには、FRAME ERRORは、スタートまたはストップのいずれかのエラーが発生して起こると記載があります。
1ビット周期であれば、スタートビットエラーのみと記載がありますが、
1.5ビット周期の場合は、スタートとストップビットエラー両方なのか、ストップビットエラーのみなのかどちらになりますでしょうか。

現状、1ビット周期のストップビットシーケンスを設定しています。
このときに、ボーレート以上の周波数パルスが入力された際に、スタートビットエラーが発生しています。
1.5ビット周期にした場合に、ストップビットエラーのみの検出となるのであれば
ボーレート以上の周波数パルスが入力されても、スタートビットとみなさずノイズとしてキャンセルされるのではないかと考えています。
そのため、1.5ビット周期のストップビットシーケンス時のスタートビットエラーの有無を知りたいと思っています。
